LOCKING DEVICE FOR BARREL PUMPS.

Application filed February 25, 1927. Serial No. 171,007.

ing its base'into the bung opening of the barrel, and with its suction pipe extending into the barrel so that the contents thereof may be withdrawn by operating the pump. The object of the improvement is to provide a locking means applicable to a container of the usual type employed for supplying lubricating oil to retail venders, which containers have a bung and a spile opening in one end.

It is common practice of unscrupulous attendance at filling stations and other places where oil is dispensed, to refill with interior oil, containers bearing the brand of a more.

expensive oil, and in this manner deceiving patrons into purchasing at'a high price an inferior article. In this manner the manufacturer or distributor who has established trade under his own brand, as well as the consumer, are deprived of their rights. The present improvement contemplates the circumvention of such practices.

This object is accomplished by-the con struction illustrated in the accompanying drawings, in which a F ig. 1 is a vertical section of a construction embodying the invention applied to a container and a pump attached thereon;

Fig. 2 is a bottom plan view of the appliance; a

Fig. 3 is a' detail showing a cross section of two sliding lock members and their inter connecting cleats, the section being on the line 3-3 of Fig. 2;

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

The invention consists of a cover 1 having a peripheral flange 2, shaped to fit over and inclose the head end 3 of a container l,which container is of the usual type proupon the secondary member. :are disposed at an angle respectmgsaid bottom plan view of one of the.

ected from Fig.

vided with a bung ring 5 and spile opening 6. The cover 1 is made of sheet metal and has formed therein an embossment 7 shaped to receive sliding lock members 8 and 9 and fa pivoted lever 10, and so as to guide said lock members. v

In one portion 11 of the cmbossmcnt is positioned the primary sliding lock member 8, which is retained therein by plates 12 that'are fixed onthe under face of the cover, and 'said member has an angular lock-bolt 13, fixed rigidly thereon, that extends through an elongated slot 14: in the cover which permits movement of the bolt therein. To the bottom face of the sliding member 8 is fixed a pendant stirrup 15 having pivoted therein a pawl 16, and a similar stirrup 17, having pivoted therein a pawl18, is fixed on the under face of the cover in alinement with the former stirrup. A- breakable notched bar 19 insertable in the stirrups and engageable with the pawls 16 and 18 arrests the primary lock member 8 in its locked position.

' An opening 20 in the cover at a point over the bar 19 admits of the insertion of a punch (not shown) so that the bar may be broken and the primary member thus released.

The secondary .sliding member 9 has guided movement in the embossment ina direction at right angles to that of the primary, member 8,'and is retained in place partly by a plate 21 fixed 011 the cover, and partly by a grooved cleat 22 fixed on'the primary member 8, which cleat under-laps the secondary member 9 and has sliding relation with another cleat 23 that is fixed sliding members and have interlocking relation with each other, so that when the primary member-is moved, the secondary member will be correspondingly moved in a direction at 'ri ht an les thereto there bein D D 7 C a gain 2 made 'in the edge of the primary member to afford clearance for the adyacent end of the secondary member.

Said cleats till In the rear portion 25 of the embossment are pivoted the lever 10 and a swinging arm 26. One end 27 of the lever bears against the adj acentside of the arm, and its opposite end 28 is socketed in one side of the secondary member 9 so that when said member is moved to locking position, the arm is correspondingly moved through the medium of the lever. A stud 29- depends from the tree end of the arm and has a head 30 on its lower end, which head, when inserted through the spile opening 6 and the stud is moved to an eccentric position therein, prevents removal of the stud therefrom.

The pump 32 shown in Fig. 1 of the drawings, is of the usual type of barrel pump provided with a threaded base 33 and suction pipe 34, the base fitting in the threaded bung ring and the pipe extending into the container, there being an aperture 35 in the cover'l for the reception of the base. In this instance the base of the pump is provided with a laterally projecting apertured lug 36 for the reception of the lock bolt 13, which bolt, when projected into the lug prevents the pump from being disconnected fromthe container. Preferably, the end of the bolt is made to protrude through the lug, and has a hole 37 made in its end for the reception of the wire of a seal (not shown) if so desired.

In Figures 6 and 7 the pump 38 is of a commontype having a drain spout 39 extending from its base 40, which is ordinarily provided for the return of oil drippings to the container. Successful employment of the present invention necessitates prevention of the passage of oil into the container from any source from the time the pump and the locking device are applied until the contents 'of the container is withdrawn and the pump and locking device are removed, and when a pump having such drain spout is used, an adapter is provided forgclosing the spout. The adapter consists of a cap 4.1 pivoted on a lug 42 that is fixed on the cover 1 and which extends over and closes the drain spout 39, and is provided with an apertured lug 43 for the reception of the lock bolt 13. In this instance, the lock-bolt and its co-opcrating connections are similar and function as in the former instance. 7

In utilizing the invention, the bung and spile are removed. from the full container, and the primary lock member is moved backwardly to its unlocked position. The breakable bar 19 is inserted through the rear stirrup 17 into the other stirrup so that the pawl 16 engages the notch 1 therein. The cover is then placed over the head of the container with the stud 29 extending through the spile openingti and the aperture 35 alined with the bung ring.

The base of the pump is inserted through the aperture-in the cover and screwed into the bung ring 5 and turned so that the aperturedlug 36 is alined with the lock-bolt 13. Finally, the lock-bolt is shoved forwardly through the lug. In the latter operation the breakable bar is drawn forwardly by the pawl 16 until the other pawl 18 engages in the notch 18 in said bar and thus preventving retraction of the primary locking mem- .moved by first shattering the breakable bar with a punch applied through the opening 20, sliding the lock-bolt from engagement with the pump, and in screwing the pump from the bung ring, after which the locking device may be lifted from the container.

that I claim is 1. Ina locking appliance of the class described for a container and pump mounted in the bung ring thereof, a coverapplicable to the head of the container, and having an opening through which the pump extends; a movablemember having locking engagement with the head of the container through the spile opening thereof; a bolt having locking engagement with the pump; amechanism in connection with said bolt sheltered by said cover, and having operable relation avith said movable member; and a breakable member having locking control of said mechanism, there being an opening in said cover through which an instrument may be applied to shatter said bar.

2. In a locking appliance of the class described for a container and pump mounted in the bung ring thereof, a cover applicable to the head of the container, and having an opening through which the pump, extends; a bolt having locking engagen'ient with the pump; a mechanism in connection with said bolt sheltered by said cover, and having locking engagement with the head of the container through the spile opening thereof; and a breakable member-having locking control of said mechanisn'i, there being an opening in said cover through which an instrument may be applied to shatter said bar.

, 3. A locking applia for acontainer and pump mounted in connection therewith, consisting of a cover applicable tothe head of the container; a locking means in connection with the cover andsheltered thereby ,and having locking engagement with said head and pump; and a breakable member locking said mechanism, and being accessible so as to be shattered by applying'an instrument, to thereby'releasesaid mechanism.

In testimony whereof I aiiix my signature.
